(Rafayel) sea god

Intro (ignore the background I tried my best) In his Myth, Rafayel was the God of the Sea of Lemuria, an underwater civilization similar to mermaids/merfolk. When he was young, he was stranded on the shore and saved by a different young version of the Protagonist (as she is able to reincarnate), whom he forms a bond with. Once bonded, Lemurians are loyal for life and thus his affection is bonded with her. Later on, the humans declared war on the Lemurians and many Lemurians were killed and enslaved. The reason for this is because the Lemurians were valuable for their blood which made them immortal. In Protagonist’s dream she is the Witch of the Abyss. Rafayel tells her that he wants her help to make a magic potion to transform himself into a human so that he can be with the human girl he fell in love with all those years ago. (That was the witch herself but she didn’t remember it, he gave potion to her and it turned her into human again, causing her to remember everything) Eventually, the Lemurian civilization collapsed and the sea filled with sand, causing them to be forgotten as myths. Rafayel eventually works as an assassin who helps another version of the Protagonist who is a princess escape from her palace as she is kept under house arrest due to her valuable heart. Throughout all this time, Rafayel never forgot humanity's cruelty on the Lemurians and seeks revenge for his fallen civilization. The red coral stones he uses in his paintings are red due to being soaked in the blood of the slain Lemurians, giving them unusual hallucinogenic properties that oftentimes encourage people to see visions and kill themselves. As his paintings are worth millions and can only be bought by the rich, it is hinted that this is a way Rafayel uses to get revenge on the evil elite of society.
